A- R. MANZO DISPENSER PACKAGE Filed Feb. 24, 1969 Sept. 8, 1970 United States Patent 3,527,342 DISPENSER PACKAGE Anthony R. Manzo, Elmhurst, Ill., assignor to Container Corporation of America, Chicago, 111., a corporation of Delaware Filed Feb. 24, 1969, Ser. No. 801,323 Int. Cl. B65d 75/36, 85/67 US. Cl. 20656 2 Claims ABSTRACT OF THE DISCLOSURE A dispenser package for a wound web of sterile material, said package being characterized by a pair of back ing sheets joined to each other along a fold line, at least one of the backing sheets being provided with an aperture therein closed by a half blister to enclose the wound web, the aperture being surrounded by a film adhered to the backing sheets and extending toward said fold line, the film being adhered to the backing sheet along a side of said aperture remote from said fold line and along areas extending normally to said fold line and flanking opposed sides of said apertures, the web being led between unadhered portions of said film, and a tear line spaced from said fold line for tearing of the backing sheets to expose said film for removal of the webs between said backing sheets. The half blister is preferably formed unitarily with the film, and is heat shrinkable about the wound web if desired.

A principal object of the invention is to provide a dispenser package for a sterile wound web of gauze or the like, the web being adapted to be in position for delivery from the package at all times, and to be visible for determination readily as to the amount remaining for dispensing.

DRAWINGS FIG. 1 is a perspective view of a dispenser package embodying the improvements according to a preferred form of the present invention;

FIG. 2 is a plan view of a blank employed in constructing the dispenser package of FIG. 1;

FIG. 3 is a plan view of the dispenser package, with the folded end tabs removed, and;

FIG. 4 is a vertical longitudinal section taken along the line 4-4 of FIG. 3 looking in the direction of the arrows.

The improved dispenser package according to the present invention is referred to by the reference numeral and is formed from a blank 10A folded on itself, as will be described, to enclose a wound web W of sterile gauze or the like. The package according to the present invention lends itself in its formation to the concomitant sterilization of web WW Blank 10A comprises backer sheets 11 and 12 joined together along a fold line 13. Each of the backer sheets 11 and 12 has a square aperture 14 therein, the apertures 14 being in register when backer sheets 11 and 12 are folded about fold line 13 into facing relationship.

Each of the apertures 14 is closed by a half blister 16, and when the two backer sheets 11 and 12 are brought into facing relationship, wound web W is held within a cavity 15 defined by the two half blisters 16.

Each half blister 16 is preferably integral with a fiat film 17 bordering aperture 14 on all sides and is adhered to its backer sheet 11 or 12 along an area 18 along a side of the aperture 14 remote from the fold line 13. Film 17 is also adhered to its backer sheet along areas 19 flanking the sides of aperature 14 and extending normally to fold line 13.

Films 17 are also adhered to each other along the areas 3,527,342 Patented Sept. 8, 1970 just described to leave an area 20 therebetween, the free end of web WW moving past said area between the films 17.

Preferably the free end of web W is located between an edge 25 of film 17 and the tear line 22.

The two backer sheets 11 and 12 are also adhered together along the peripheries thereof along areas 21.

The assembly by the package in the manner described is preferably done with films 17 and backer sheets 11 capable of adhering by the application of heat alone. Films 17 are not only capable of heat scaling to themselves but to backer sheets 11 and 12, and the latter preferably has a thermoplastic coating capable of heat sealing.

The wound web WW placed in the cavity may be sterlized during the sealing process described by the heat thereof, or by a suitable gas. If desired the half blisters 16 may be heat shrunk about web WW when in the cavity 15.

The dispenser package 10 is opened along a tear line 22 spaced from the fold line 13, so that a folded end tab 24 is removed in the tearing operation. When such is done, the free end of web WW located between films 17, as seen in FIG. 4, will be protected against contamination since its contact with unsterile surfaces outside the package will be precluded by the enclosing films.

The dispenser package may be suspended from a hook or similar device by means of the hole 23 therein.

If desired, only one of the backer sheets 11 or 12 may be provided with the aperture 14, and the web WW may be enclosed in but one blister 16, the end of web WW being brought between backer sheets 11 and 12 and to extend toward fold line 13.

I claim:

1. A dispenser package for wound web of sterile material, comprising:

(a) a pair of backer sheets foldably joined to each other along a fold line;

(b) each of said backer sheets having an aperture adapted to be in registery with each other when said sheets are folded into facing relationship;

(c) a tear line in each of said backer sheets spaced from said fold line and in registry with each other when said sheets are folded into facing relationship;

(d) a film positioned on facing side of each backer sheet and extending beyond said tear line toward said fold line;

(e) said film forming a half-blister for closing each of said apertures so as to enclose therebetween a wound web of sterile material when said backer sheets are folded into facing relationship;

(f) said films being adhered to each other along the sides of said apertures remote from said fold line and along areas extending normally to said fold line and flanking opposed sides of said apertures and being free from adherence to each other in the area along said tear line to permit dispensing of material between unadhered portions of said films;

(g) the terminal portions of said films extending outside said backer sheets when said package is opened along said tear line and enclosing therebetween the free end of material to be dispensed so as to prevent contact between said material and unsterile surfaces outside said package.

2. A dispenser package for wound web of sterile material, comprising:

(a) a pair of backer sheets foldably joined to each other along a fold line;

(b) at least one of said backer sheets having an aperture formed therein;

(c) a tear line in each of said backer sheets spaced 3 from said fold line and in registry with each other when said sheets are folded into facing relationship;

(d) a film positioned on facing side of each backer sheet and extending beyond said tear line toward said fold line;

(e) said film forming a half-blister for closing said aperture so as to enclose therein a wound web of sterile material when said backer sheets are folded into facing relationship;

(f) said films being adhered to each other along the side of said aperture remote from said fold line and along areas extending normally to said fold line and flanking opposed sides of said aperture and being free from adherence to each other in the area along said tear line to permit dispensing of material between unadhered portions of said films;

-(g) the terminal portions of said films extending outside said backer sheets when said package is opened along said tear line and enclosing therebet-ween the free end of material to be dispensed so as to pre- 4 vent contact between said material and unsterile surfaces outside said package.
